Type Alias: NavigationResult<TStepId>

type NavigationResult<TStepId> =
  | {
  from: TStepId | null;
  ok: true;
  to: TStepId;
}
  | {
  error?: unknown;
  from: TStepId | null;
  ok: false;
  reason: NavigationFailureReason;
  to: TStepId | null;
};

Defined in: core/src/core/types.ts:51

Result of every navigation verb (and of graph send).

The failure arm carries from/to so a caller awaiting the result can log which target was rejected without also subscribing to navigationBlocked. to is null when the machine never resolved one — a graph send with no enabled candidate, for instance.
